    Loads are certainly not free on many CPU models. This is made worse
    by the fact that C alias analysis has to be so pessimistic, especially
    given that the kernel is compiled with -fno-strict-aliasing.

    I implemented the thread_info stuff, and I checked out the
    performance, have you?
